Description

Technical Field

[0001] This invention relates to the field of flange production and processing equipment technology, specifically to a continuous tapping device for flange production and processing. Background Technology

[0002] In the flange manufacturing process, tapping is one of the key steps. Tapping is the process of machining internal threaded holes on the flange so that it can be connected with bolts later. The accuracy of this step directly determines the assembly quality and performance of the flange.

[0003] Existing continuous flange tapping equipment typically uses photoelectric sensors to detect the flange's rotation into position during the tapping process. By installing photoelectric sensors at specific locations, the sensor sends a signal when the flange rotates to a position that blocks or reflects light, thus determining whether the flange is in position. However, the flange tapping process generates a large amount of metal shavings and oil mist. These impurities adhere to the sensor surface, interfering with its normal operation, leading to unstable detection signals or misjudgments, resulting in inaccurate detection results. On the other hand, photoelectric sensors have certain requirements regarding the flange's material, color, and surface finish. If the flange material has poor light absorption or reflection characteristics, or if there are scratches or stains on the surface, it will affect the sensor's detection effect and make it impossible to reliably detect the rotation into position.

[0004] Therefore, in view of this, the present invention proposes a continuous tapping device for flange production and processing to make up for and improve the deficiencies of the prior art. Summary of the Invention

[0009] Preferably, an adjustment disc is fixedly connected to the outer surface of the upper end of the linkage shaft. Multiple arc-shaped grooves are evenly spaced along the circumference of the adjustment disc. A sliding rod is slidably connected through the arc-shaped grooves and the support plate. An inner support plate is fixedly connected to the top of the sliding rod.

[0010] Preferably, the first fixing frame has symmetrically opened connecting grooves on the side facing the moving plate. The bottom wall of the connecting groove is fixedly connected to the first elastic telescopic column. Multiple suction cups are fixedly connected at equal intervals along the circumference on the upper surface of the support tray. Multiple L-shaped fixing plates are fixedly connected at equal intervals along the circumference on the lower surface of the support tray. A second elastic telescopic column is fixedly connected to the end of the L-shaped fixing plate away from the axis of the support tray. A positioning protrusion is fixedly connected to the end of the second elastic telescopic column away from the L-shaped fixing plate.

[0011] Preferably, a second fixing frame is fixedly connected to the bottom wall of the fixed cover. The second fixing frame is arranged opposite to the first fixing frame, and a positioning groove adapted to the positioning protrusion is opened on the side of the second fixing frame facing the first fixing frame.

[0012] Preferably, the synchronous rinsing and dandruff removal mechanism further includes a linkage disk fixedly connected to the lower surface of the support disk. Multiple arc-shaped toothed plates are fixedly connected at equal intervals along the circumferential direction on the outer surface of the linkage disk. A half gear is rotatably connected to the bottom wall of the fixed cover, and the half gear meshes with the arc-shaped toothed plates.

[0013] Preferably, a mounting bracket is fixedly connected to the inner bottom wall of the fixed cover, a torsion spring shaft is fixedly connected to the upper surface of the half gear, the top of the torsion spring shaft is fixedly connected to the bottom of the opening and closing member, the bottom of the opening and closing member passes through the mounting bracket, and the opening and closing member is rotatably connected to the mounting bracket.

[0014] Preferably, a water pump is fixedly connected to the bottom wall of the fixed cover, the fixed pipe is fixedly connected to the outlet end of the water pump, the free end of the fixed pipe is fixedly connected to a nozzle, the inlet end of the water pump is fixedly connected to a water guide pipe, an annular sealing plate is fixedly connected to the upper end of the annular water tank, and multiple seepage holes are equally spaced along the circumference of the annular sealing plate, and the seepage holes are connected to the annular water tank, and the drain hole is obliquely shaped.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) By setting up the rotation position detection mechanism, using the design of the bearing tray, push ball, moving plate, first fixed frame and contact point, when the flange is rotated to the position, the push ball pushes the moving plate to move and presses the contact point, so that the indicator light is lit. This provides the staff with an intuitive and clear rotation position signal, avoids processing errors caused by the inability to accurately judge the flange rotation state, improves production efficiency and product quality, and the lighting status of the indicator light can provide real-time feedback on whether the flange rotation is in place, so that the staff can react quickly according to the status of the indicator light and perform tapping operations in a timely manner, reducing the waiting and judgment time, and making the entire production process smoother and more efficient. Among them, the electric push rod pushes the L-shaped toothed plate, which drives the adjustment plate to rotate through the driven gear and the linkage shaft, thereby causing the slide rod to slide in the arc groove and push the inner support plate to fit the inner arc surface of the flange for internal support and fixation. This internal support method can provide uniform and stable support force from inside the flange, effectively preventing the flange from shaking during processing, ensuring the stability of the flange during rotation and tapping, and improving processing accuracy. The design incorporates an L-shaped fixing plate and a second elastic telescopic column at the bottom of the bearing tray. When the bearing tray and flange rotate into position, the positioning protrusion engages with the positioning groove on the second fixing frame. This secondary positioning design further ensures the accuracy of the flange's position after rotation, providing a more reliable positioning guarantee for tapping. It prevents the tapping accuracy from being affected by flange position deviation during the tapping process. The engagement of the positioning protrusion with the positioning groove restricts the bearing tray's freedom of movement, effectively preventing the flange from shaking due to external forces during tapping. This ensures the stability and continuity of the tapping process and improves the tapping quality.

[0016] (2) By setting up a synchronous flushing and chip removal mechanism, the cutting fluid spraying and flange rotation are synchronized through the meshing of the arc toothed plate and the half gear on the linkage plate. During the flange rotation and tapping process, the cutting fluid can be continuously and accurately sprayed onto the tapping part, and the chips and residues generated by tapping are cleaned in time. This avoids the impact of chip accumulation on tapping accuracy and processing quality, greatly improves processing efficiency, and achieves efficient coordination between processing and cleaning. Furthermore, when the flange starts to rotate and tap, the arc toothed plate can immediately drive the half gear to rotate, open the internal channel of the fixed pipe, and spray the cutting fluid in time. When the tapping is finished or needs to be paused, the reverse movement of the relevant components can close the channel in time and stop the cutting fluid spraying. This precise timing control avoids the waste of cutting fluid and also ensures the optimal cleaning effect. The design, utilizing opening and closing components, a fixed pipe, an annular water groove, and drainage holes, effectively collects cutting fluid flowing from the tapping area and residual liquid on the surface of the support plate. Through the seepage holes on the annular sealing plate, the liquid can smoothly flow into the annular water groove, preventing it from flowing around on the support plate, maintaining a clean working environment, and reducing the corrosion and impact of the liquid on other components. The annular water groove is connected to the equidistant, angled drainage holes on the outer ring surface, which can centrally discharge the collected liquid. This centralized drainage method facilitates the recycling and treatment of cutting fluid, reduces production costs, and meets environmental protection requirements. The angled design also accelerates the drainage speed and prevents liquid from accumulating in the annular water groove. Attached Figure Description

The moving plate 515 is arranged between the support tray 511 and the first fixed frame 517. The contact point 524 is arranged on the side of the first fixed frame 517 facing the moving plate 515. The rotation positioning detection mechanism 5 also includes a support plate 502 rotatably connected to the bottom wall of the fixed cover 4, a drive motor 501 fixedly connected to the top wall of the workbench 1, and the output end of the drive motor 501 fixedly connected to the support plate 502. Fixed columns 512 are fixedly connected at equal intervals along the circumference between the top of the support plate 502 and the support tray 511. A linkage shaft 506 is rotatably connected to the upper surface of the support disk 502. A driven gear 505 is fixedly connected to the lower outer surface of the linkage shaft 506. An electric push rod 503 is also fixedly connected to the upper surface of the support disk 502. An L-shaped toothed plate 504 is fixedly connected to the output end of the electric push rod 503. The L-shaped toothed plate 504 meshes with the driven gear 505. The L-shaped toothed plate 504 is slidably connected to the upper surface of the support disk 502. An adjusting disc 507 is fixedly connected to the outer surface of the upper end of the linkage shaft 506. Arc grooves 508 are evenly spaced along the circumference of the adjusting disc 507. A sliding rod 509 is slidably connected between the arc groove 508 and the support plate 511. The bottom of the sliding rod 509 is slidably connected to the arc groove 508. An inner support plate 510 is fixedly connected to the top of the sliding rod 509. The first fixing frame 517 is fixedly connected to the inner bottom wall of the rear end of the fixing cover 4. The first fixing frame 517 has a symmetrically opened connecting groove 518 on the side facing the moving plate 515. The bottom wall of the connecting groove 518 is fixedly connected to the moving plate 515 with a first elastic telescopic column 516. The upper surface of the support tray 511 is fixedly connected with suction cups 513 at equal intervals along the circumference, and the lower surface of the support tray 511 is fixedly connected with L-shaped fixing plates 519 at equal intervals along the circumference. The end of the L-shaped fixing plate 519 away from the axis of the support tray 511 is fixedly connected with a second elastic telescopic column 520, and the end of the second elastic telescopic column 520 away from the L-shaped fixing plate 519 is fixedly connected with a positioning protrusion 521. A second fixing bracket 522 is fixedly connected to the inner bottom wall of the front end of the fixing cover 4. The second fixing bracket 522 has a positioning groove 523 on the side facing the first fixing bracket 517, and the positioning protrusion 521 is adapted to the positioning groove 523.

[0020] Please refer to Figure 1 , Figure 2 , Figure 4 as well as Figure 5 Even better: The worktable 1 is equipped with an indicator light that is electrically connected to the contact 524. When the contact 524 is touched and pressed, the indicator light turns on, indicating that the rotation is in place. In addition, the electric push rod 503 is used to control the movement of the inner support plate 510 to provide inner support for the flange to be tapped, and the drive motor 501 is used to control the rotation of the flange to be tapped.

[0021] The effects achieved by this embodiment are as follows: Compared with the prior art, by setting up the rotation position detection mechanism 5, and utilizing the design of the support tray 511, push ball 514, moving plate 515, first fixed frame 517 and contact point 524, when the flange is rotated into position, the push ball 514 pushes the moving plate 515 to move and presses the contact point 524, causing the indicator light to light up. This provides the operator with an intuitive and clear rotation position signal, avoiding processing errors caused by the inability to accurately judge the flange rotation state, improving production efficiency and product quality. The lighting status of the indicator light can provide real-time feedback on whether the flange rotation is in place, allowing the operator to react quickly based on the indicator light status and perform tapping operations in a timely manner, reducing waiting and judgment time, and making the entire production process smoother and more efficient. In this process, the electric push rod 503 pushes the L-shaped toothed plate 504, which in turn drives the adjusting plate 507 to rotate via the driven gear 505 and the linkage shaft 506. This causes the slide rod 509 to slide in the arc groove 508, pushing the inner support plate 510 to conform to the inner arc surface of the flange for internal support and fixation. This internal support method can provide uniform and stable support force from inside the flange, effectively preventing the flange from shaking during processing, ensuring the stability of the flange during rotation and tapping, and improving processing accuracy. The support tray 511 is equipped with an L-shaped fixing plate 519 and a second elastic telescopic column 520 at its bottom. When the support tray 511 rotates into position with the flange, the positioning protrusion 521 can engage with the positioning groove 523 on the second fixing frame 522. This secondary positioning design further ensures the positional accuracy of the flange after it rotates into position, providing a more reliable positioning guarantee for tapping. It prevents the tapping accuracy from being affected by the flange position shift during the tapping process. The engagement of the positioning protrusion 521 with the positioning groove 523 restricts the freedom of the support tray 511, effectively preventing the flange from shaking due to external forces during the tapping process, ensuring the stability and continuity of the tapping process, and improving the tapping quality.

[0022] Embodiment 2 of the present invention: Please refer to Figures 1 to 8 As shown, the synchronous rinsing and dandruff removal mechanism 6 includes an opening and closing element 606, a fixed pipe 609, an annular water tank 611, and a drain hole 614. The opening and closing element 606 is rotatably connected to the fixed pipe 609. The fixed pipe 609 is located on the right side of the support tray 511. The annular water tank 611 is opened at the upper end of the support tray 511. The drain hole 614 is opened at equal intervals along the circumference on the outer ring surface of the support tray 511. The drain hole 614 is oblique and is connected to the annular water tank 611. The synchronous rinsing and dandruff removal mechanism 6 also includes a linkage disk 601 fixedly connected to the lower surface of the support disk 502. Arc-shaped toothed plates 602 are fixedly connected to the outer surface of the linkage disk 601 at equal intervals along the circumference. A half gear 603 is rotatably connected to the inner bottom wall of the right end of the fixed cover 4, and the half gear 603 is adapted to the arc-shaped toothed plates 602. A mounting bracket 605 is also fixedly connected to the inner bottom wall of the right end of the fixed cover 4. A torsion spring shaft 604 is fixedly connected to the upper surface of the half gear 603. The top of the torsion spring shaft 604 is rotatably connected to the inner bottom wall of the left end of the mounting bracket 605. The opening and closing part 606 is rotatably connected to the left end of the mounting bracket 605, and the bottom of the opening and closing part 606 is fixedly connected to the torsion spring shaft 604. A water pump 607 is also fixedly connected to the inner bottom wall of the right end of the fixed cover 4. A fixed pipe 609 is fixedly connected to the top of the water pump 607. A nozzle 610 is fixedly connected to the left end of the fixed pipe 609. A water guide pipe 608 is also fixedly connected to the water pump 607. An annular sealing plate 612 is fixedly connected to the upper end of the annular water tank 611. Seepage holes 613 are evenly spaced along the circumference of the annular sealing plate 612, and the seepage holes 613 are connected to the annular water tank 611.

[0023] Please refer to Figures 1 to 3 Even better: the opening and closing element 606 includes a valve stem and a valve disc. The valve stem is rotatably mounted on the mounting bracket 605, and the bottom of the valve stem is fixedly connected to the torsion spring shaft 604. When the arc-shaped toothed plate 602 drives the half gear 603 to rotate, the torsion spring shaft 604 rotates synchronously at the bottom of the mounting bracket 605, thereby driving the valve stem to rotate and causing the valve disc to rotate inside the fixed tube 609. It should be noted that the valve disc has a circular structure and is arranged in a cross-shaped axis with the fixed tube 609. That is, the valve disc can initially block the fixed tube 609. When the valve disc is driven to rotate, it will open the internal channel of the fixed tube 609, allowing water to pass through and spray out from the nozzle 610. In addition, the lower end of the fixed cover 4 is fixedly connected to the drain pipe, and a filter plate is provided between the water pump 607 and the water guide pipe 608. The pumping-related steps and design are existing technologies and will not be elaborated on here.

[0024] The effects achieved by this embodiment are as follows: Compared with the prior art, by setting up the synchronous flushing and chip removal mechanism 6, and by meshing the arc-shaped toothed plate 602 on the linkage plate 601 with the half gear 603, the cutting fluid spraying and flange rotation are synchronized. During the flange rotation and tapping process, the cutting fluid can be continuously and accurately sprayed onto the tapping part, and the chips and residues generated during tapping are cleaned in time, avoiding the impact of chip accumulation on tapping accuracy and processing quality, greatly improving processing efficiency, and realizing efficient synergy between processing and cleaning. Furthermore, when the flange starts to rotate and tap, the arc-shaped toothed plate 602 can immediately drive the half gear 603 to rotate, open the internal channel of the fixed tube 609, and spray out the cutting fluid in time. When tapping ends or needs to be paused, the reverse movement of the relevant components can close the channel in time and stop the cutting fluid spraying. This precise timing control avoids the waste of cutting fluid and also ensures the optimization of the cleaning effect. The design of the opening and closing element 606, the fixing pipe 609, the annular water groove 611, and the drain hole 614 effectively collects the cutting fluid flowing down from the tapping part and the residual liquid on the upper surface of the support plate 511. Through the seepage hole 613 on the annular sealing plate 612, the liquid can flow smoothly into the interior of the annular water groove 611, preventing the liquid from flowing around on the support plate 511, keeping the working environment clean, and reducing the corrosion and impact of the liquid on other parts. The annular water groove 611 is connected to the equidistant oblique drain holes 614 on the outer ring surface, which can centrally discharge the collected liquid. This centralized drainage method facilitates the recycling and treatment of cutting fluid, reduces production costs, and meets environmental protection requirements. The oblique design can also speed up the drainage speed and prevent the liquid from accumulating in the annular water groove 611.

[0025] The complete usage steps and working principle of the above embodiments are as follows: The following is the working process of the rotation positioning detection mechanism 5: In the continuous tapping process of flanges to be tapped, the flange can first be placed on top of the support tray 511, with the bottom surface of the flange in contact with the suction cup 513 installed on the upper surface of the support tray 511. The suction cup 513 initially adsorbs and positions the flange. Then, by activating the electric push rod 503, the L-shaped toothed plate 504 can be pushed to slide on the upper surface of the support plate 502. Figure 5As shown, a linkage shaft 506 is rotatably mounted on the support plate 502, and a driven gear 505 and an adjusting plate 507 are sequentially fixedly connected to the outer surface of the linkage shaft 506 from bottom to top. Simultaneously, the driven gear 505 meshes with an L-shaped toothed plate 504. Therefore, when the electric push rod 503 moves and pushes the L-shaped toothed plate 504, the meshing between the teeth drives the driven gear 505 to rotate synchronously. This, in turn, drives the adjusting plate 507 to rotate synchronously below the support plate 511 via the linkage shaft 506. Furthermore, the adjusting plate 507 has multiple arc-shaped grooves 508, and these grooves are connected to the support plate 511. A sliding rod 509 is slidably installed between the flange and the inner support plate 510, which is fixedly installed above the sliding rod 509 to limit the position of the flange. Therefore, when the driven gear 505 rotates and drives the adjusting plate 507 to rotate, the position of the arc groove 508 changes accordingly, which can push the sliding rod 509 to slide synchronously between the adjusting plate 507 and the support plate 511, change the position of the inner support plate 510, and make the outer arc surface of the inner support plate 510 fit against the inner arc surface of the flange to be tapped, so as to complete the inner support and fixation of the flange, increase the stability of the flange during processing, and ensure that the flange remains stable and does not wobble during subsequent rotation. After the flange is internally fixed, the drive motor 501 can be started to drive the support plate 502 to rotate synchronously with the internal support structure installed on it, such as... Figure 2 and Figure 6 As shown, since the support plate 511 is fixedly mounted on the support plate 502 by several fixed columns 512, the fixed flange, support plate 511 and support plate 502 can be temporarily assembled into an integral structure. Therefore, when the drive motor 501 is running, the support plate 502 can be rotated synchronously to drive the support plate 511 to rotate, thereby making the flange to be tapped rotate synchronously and cooperate with the operating frame 2 and the tapping head 3 to tap the flange. During the above process, when the flange is rotated, according to Figure 2 and Figure 4As shown, multiple push balls 514 are fixedly arranged at equal intervals along the circumference of the outer ring surface of the support tray 511. A movable plate 515 is arranged between the push balls 514 and the first fixed frame 517, and the movable plate 515 and the first fixed frame 517 are connected by two symmetrical first elastic telescopic columns 516. Under the connection of the first elastic telescopic columns 516, the movable plate 515 can be movable. When the push balls 514 are not in contact with the movable plate 515, the movable plate 515 is set away from the first fixed frame 517, and the movable plate 515 is not in contact with the contact point 524. The indicator light installed on the workbench 1 is also... The indicator light does not illuminate. When the flange rotates, the push ball 514 rotates and moves, contacting the moving plate 515 and pushing the moving plate 515 towards the first fixed frame 517. When the flange is fully rotated, the first elastic telescopic column 516 is fully compressed into the inside of the connecting groove 518, and the moving plate 515 is fully attached to the front surface of the first fixed frame 517, pressing the contact 524, which causes the indicator light connected to it to light up. At this time, the operator can know the actual status of the flange rotation based on the lighting status of the indicator light. according to Figure 6 and Figure 7 As shown, multiple L-shaped fixing plates 519 are fixedly arranged at equal intervals along the circumference at the bottom of the bearing tray 511, and a second elastic telescopic column 520 is fixedly arranged at the end of the L-shaped fixing plate 519 away from the axis of the bearing tray 511. During the synchronous rotation of the bearing tray 511 and the flange (i.e., during the positioning detection process), the L-shaped fixing plate 519 synchronously follows the rotation displacement with the center of the bearing tray 511 as the axis. When the rotation is in place, since the positioning groove 523 is opened on the second fixing frame 522, and the end of the second elastic telescopic column 520 is fixedly arranged with a positioning protrusion 521 that matches the positioning groove 523, the positioning protrusion 521 can be moved and locked into the interior of the positioning groove 523 by the rotation displacement of the L-shaped fixing plate 519, which further limits the position of the bearing tray 511 after it has been rotated to the position, further ensuring the stability of the flange after it has been rotated to the position, and preventing the tapping accuracy from being affected by the flange shaking during the tapping process. Please refer to the above work process. Figures 1 to 8 .

[0026] The following is the working process of the synchronous rinsing and dandruff removal mechanism 6: It should be noted in advance that the opening and closing component 606 includes a valve stem and a valve disc. The valve stem is rotatably mounted on the mounting bracket 605, and the bottom of the valve stem is fixedly connected to the torsion spring shaft 604. When the arc-shaped toothed plate 602 drives the half gear 603 to rotate, the torsion spring shaft 604 rotates synchronously at the bottom of the mounting bracket 605, thereby driving the valve stem to rotate and causing the valve disc to rotate inside the fixed tube 609. It should be noted that the valve disc has a circular structure and is arranged in a cross-shaped axis with the fixed tube 609. That is, the valve disc can initially block the fixed tube 609. When the valve disc is driven to rotate, it will open the internal channel of the fixed tube 609, allowing water to pass through and spray out from the nozzle 610. During the tapping process of the flange, the flange is rotated by the drive motor 501. Because a linkage plate 601 is fixedly installed on the lower surface of the support plate 502, and multiple arc-shaped toothed plates 602 are fixedly installed at equal intervals along the circumference of the outer ring surface of the linkage plate 601, the support plate 502 rotates synchronously with the drive motor 501, driving the linkage plate 601 to rotate simultaneously. The arc-shaped toothed plates 602 also move synchronously accordingly. Figure 2 as well as Figure 3 As shown, a water pump 607 and a mounting bracket 605 are sequentially installed inside the fixed housing 4. A water guide pipe 608 is fixedly connected to the water pump 607 for introducing cutting fluid. The introduced cutting fluid is transmitted through a fixed pipe 609 and finally sprayed out into the nozzle 610. Initially, the internal channel of the fixed pipe 609 is closed by the opening and closing element 606. At the same time, the lower end (valve stem) of the opening and closing element 606 is rotatably mounted through the left end of the mounting bracket 605, and the upper end (valve disc) is rotatably mounted through the fixed pipe 609. A torsion spring shaft 604 is rotatably mounted at the bottom left end of the mounting bracket 605, and the bottom of the torsion spring shaft 604 is fixedly connected to the half gear 603. The top of the torsion spring shaft 604 is fixedly connected to the opening and closing element 606. The half gear 603 is rotatably mounted on the bottom wall of the fixed cover 4. At the same time, the half gear 603 is adapted to the arc-shaped toothed plate 602. Therefore, when the support plate 502 rotates, the arc-shaped toothed plate 602 moves synchronously to follow the displacement. By utilizing the meshing between the teeth, the half gear 603 can be driven to rotate around the torsion spring shaft 604. At this time, the torsion spring shaft 604 rotates synchronously, which can drive the opening and closing part 606 to rotate synchronously, opening the internal channel of the fixed pipe 609, allowing the cutting fluid to pass through smoothly and spraying it from the nozzle 610 to the tapping area of ​​the flange. This completes the cleaning of the residue at the tapping area, thereby achieving the treatment of the tapping residue while rotating the flange. During the cleaning process, since the upper end of the support tray 511 is provided with an annular water groove 611, and the upper end of the annular water groove 611 is fixedly provided with an annular sealing plate 612 (and the connection between the annular sealing plate 612 and the support tray 511 is set as an inclined surface to facilitate the flow of residual liquid on the upper surface of the support tray 511), and the annular sealing plate 612 is provided with evenly distributed seepage holes 613 that communicate with the annular water groove 611, the flowing cutting fluid can flow into the interior of the annular water groove 611 through the seepage holes 613. Since the outer ring surface of the support tray 511 is also provided with equidistant oblique drainage holes 614, and the drainage holes 614 are connected to the annular water groove 611, the liquid accumulated inside the annular water groove 611 can be effectively discharged. Please refer to the above work process. Figures 1 to 8 .
